yes, I read this article before starting the test calculations of intrinsic frequencies.
My interest in this class of calculations arose from the need to estimate the parameters of the fragments of structures. The more different parameters I have, the more reliable will be correlations and conclusions.
I also suspected that the lack of frequencies for angular deformations cannot be random and you have confirmed my suspicions. As for me I do not quite understand why they are not. I don't understand the theory well enough. Perhaps you're right.
Thank you very much for your comments!
